Proben, short for proventriculus, is a type of Filipino street food that uses the proventriculus (a part of the chicken’s digestive system). The proventriculus is seasoned, coated in flour or breadcrumbs, and then deep-fried to a crispy, golden brown. It has a distinct flavor and chewy texture, with a crispy outer layer that’s perfect for dipping into vinegar with chilies, onions, and garlic. Proben is particularly popular in southern regions of the Philippines and is cherished by fans of offal, offering a unique taste and texture that’s different from typical chicken parts.
